AI in your IDE (e.g. Cursor) vs AI in your terminal (Claude Code) — what’s the better flow?

I stick with IDE-based AI — it keeps me in the flow.

Been defaulting to Claude Code for everything lately, partly because once you're running multi-agent setups the terminal-native approach just makes more sense - you're already orchestrating things via shell anyway. The IDE feels too click-y when you're coordinating multiple agents across different tasks. That said, Cursor still wins for quick targeted edits where I know exactly what I want - no need to context-switch into a whole conversation for something that's two lines.

Depends what you are optimizing for. For exploration and prototyping I keep going back to terminal - Claude Code in a bare shell forces you to be specific about what you want, which is actually useful. For production work on an existing codebase, IDE wins because the context window problem is real and Cursor handles it better with file references and inline diffs. The interesting pattern I have noticed: IDE for iterating, terminal for generating. They are not really competing.

I use both and they serve different purposes.

Cursor (IDE): Best for when I am editing existing code. Inline completions, cmd+K for quick edits, tab-tab-tab through suggestions. It feels like pair programming. Great for iterating on UI code, fixing bugs, and refactoring.

Claude Code (terminal): Best for greenfield work and multi-file changes. When I need to scaffold a new feature, create multiple files, or make architectural changes across the codebase. It thinks about the project as a whole rather than one file at a time.

For building TokenBar (my macOS menu bar app), I used Claude Code for the initial architecture and adding new provider integrations (each one needs a new API client, parser, and UI component). Then Cursor for polishing the UI, tweaking animations, and fixing edge cases.

The cost adds up though. Cursor Pro + Claude API usage + ChatGPT for occasional second opinions = easily $100+/month. That is actually why I built TokenBar in the first place. I had no idea I was spending that much until I tracked it all in one place (tokenbar.site).

Short answer: IDE AI for editing, terminal AI for creating. Use both.

I use both and they solve different problems.

Cursor (IDE): Best for when I'm working inside a file and need inline completions, quick refactors, or want to chat about a specific function. The tab completion is addictive once you get used to it. Great for "I know what I want to change, help me do it faster."

Claude Code (terminal): Best for bigger tasks. "Create a new API endpoint with tests and update the router." It can touch multiple files, run commands, and reason about the whole project structure. I reach for this when the task is more than a single-file edit.

My actual flow: I use Cursor for 80% of daily coding and Claude Code for the 20% that involves multi-file changes or project scaffolding. They complement each other really well.

The hidden cost nobody talks about: both of these burn through API credits. A heavy day with Cursor + Claude Code can easily cost $8-15 in API usage. I started tracking this with TokenBar (tokenbar.site) because I wanted to know my actual "AI tooling cost" per month. Turns out it was around $150/month across all providers. Knowing that number changed how I use these tools - I'm more intentional now about when I lean on AI vs just writing the code myself.

Neither approach is "better." The real skill in 2026 is knowing when to use which.

Both, but for different modes of work.

IDE-based AI (Cursor) is better when you're in "follow" mode — reading existing code, making targeted edits, navigating a large codebase. The visual context helps you stay oriented.

Terminal AI (Claude Code) is better when you're in "lead" mode — you know what you want built, you describe it, and the AI executes across multiple files. The terminal feels more like delegating to a capable junior dev.

The real workflow is switching between both depending on whether you're exploring or building. Neither alone covers the full pair programming experience.

As a developer building a high-performance no_std Rust kernel (Aegis Omni-Core), I’ve found that the "Terminal vs IDE" choice really depends on the complexity of the abstraction layer.

For 9.4 GB/s FHE logic, I’m team Terminal (Claude Code) for the "Thinking" phase. When you’re dealing with manual memory alignment and SIMD intrinsics, you need an agent that can grasp the entire architectural context across multiple crates. Terminal-based AI feels more like an architect you're debating with.

However, I keep Cursor for the "Surgical" phase. When I’m fine-tuning a specific hot-path or debugging a register allocation issue, having the AI right there in the editor to suggest quick syntax fixes is unbeatable.

My hybrid workflow:

1. Terminal for structural planning and complex refactoring (where IDE agents often hallucinate the context).

2. IDE for real-time linting and micro-adjustments.

Curious for those using Claude Code: Have you noticed a significant difference in how it handles strict compiler constraints (like no_std or specialized target features) compared to Cursor's indexing?
